Epidemic season 2021–2022: Frequency of co-infection by respiratory viral pathogens

BACKGROUND: This study was conducted to determine the characteristics of various viral respiratory pathogens spreading during epidemic season 20212022 and frequency co-infection with SARS-CoV-2 influenza.
 AIM: To assess development influenza cases in patients acute infections between 2021 2022.
 MATERIALS AND METHODS: Traditional hospital epidemiological surveillance methods for were used.
 RESULTS: The characterized by early activity A(H3N2) virus emergence rapid spread omicron variant SARS-CoV-2. distribution different clearly traced: (18.8%) predominant, followed viruses (10.6%) other (0.43.7%). With respect A (H3N2) B viruses, heterogeneity their populations drift variability relation vaccine strains noted.
 DISCUSSION: low, i.e., it no more than 0.1%according traditional surveillance, 9.2% surveillance. rationale updating composition vaccines countries Northern Hemisphere 20222023 identified.
 CONCLUSION: At present, diagnosis is important given availability effective drugs a direct mechanism action prevention treatment this pathogen. Timely use anti-influenza will reduce risks severe course, complications, death, including
